P0841, P0733 are transmission related codes.
P0841 (LR pressure switch rationality)
P0733 Gear 3 Incorrect ratio
Nothing there points to the engine that I can tell.
Unless you have an electrical problem that affecting the engine too? In which case, the knock could be misbehaving injectors or bad timing. If that were the case I'd expect to see codes for the engine also...
Are those are 'old' codes from the earlier transmission failure that just haven't been cleared? Loss of oil pressure when the line let go might account for them.
I guess since you're in there, might as well measure clearances against the specs and see if things appear rational.. bona-fide mystery..

Sounds like you're wanting to know end-play on the crank journals? (0.003-0.011 in.)
Do you have a service manual?
I think the information you're seeking is around pages 9-182 'Engine Specifications' '2.8L Common Rail Diesel Engine' (page 1447 on the PDF).

I have the service manual. The crank end play is fine. It is the three center main bearings that have me concerned with their floating around movement. Doesn't make sense to me that the rods would all be fine and the three center main bearings would be worn. My vehicle has 115,000 miles on it. I recently blew a transmission oil line and now I get P0841, P0733, and P0000. I was hoping the noise was coming from the tranny, but when I talked to local diesel mechanics with 30 years experience, I was told that transmissions do not make knocking noises when they have something wrong. That is why I decided to open up the motor before a rod came through the block. I will make some phone calls tomorrow...
